Randomized Controlled Trial
Acupuncture and knee osteoarthritis: a three-armed randomized trial.
Despite the popularity of acupuncture, evidence of its efficacy for reducing pain remains equivocal. ⋯ Compared with physiotherapy and as-needed anti-inflammatory drugs, addition of either TCA or sham acupuncture led to greater improvement in WOMAC score at 26 weeks. No statistically significant difference was observed between TCA and sham acupuncture, suggesting that the observed differences could be due to placebo effects, differences in intensity of provider contact, or a physiologic effect of needling regardless of whether it is done according to TCA principles.
